I have some computers with a massive amount of memory, and I have some
jobs that could use very large matrix sizes. Can R handle matrices of
larger than 2GB? If I were to create a matrix of 1,000,000 x 1,000, it
would use about 8GB. Can R work with an array of that size if I have
compiled R

By learning enough to see whether that makes a difference for your

Segmentation fault
This is a R bug or an error in my for function?
All seg faults are bugs.

I think you need the Matrix package:

Ah ha! This leads to the latest version of my little one-liner (called

That is a really beautiful page. If the author is willing to update it to
include some of the new Octave functionality -- specifically N-dimensional
arrays -- I'm sure I can help

Hi there,
Suppose mu is constant, and error is normally distributed with mean 0 and
fixed variance s. I need to find a statistics that:
Y_i = mu + beta1* I1_i beta2*I2_i + beta3*I1_i*I2_i + +error, where I_i is 1
Y_i is from group A, and 0 if Y_i is from
Many thanks for the suggestions. Here is a related question:

What you really want to do might be solved by write.table(), e.g.
x - matrix(rnorm(25*2),c(25,2));
write.table(file=stdout(), x, row.names=FALSE, col.names=FALSE);
Thanks. That does what I want.
There is one remaining problem for my echo method.

A note of concern: When writing batch scripts like this, be explicit
and use the print() statement. A counter example to compare

I'm new to the list. I've used R and S-PLUS a bit for about 15 years but
am now working to make R my main program for all numerical and statistical
computing. I also use Octave for this kind of work and I recommend it (it
is also under the GPL). Here's my question: In Octave I can write
